Platform features
See the grid, then score every parcel against it.
Power Lines Map Layer
SiteData overlays Texas's electric transmission network on the map, color-coded by voltage class — 100–161 kV, 220–287 kV, 345 kV, and 500 kV and above. Toggle the layer on and click any line to see its voltage, operator, and connected substations. Interconnecting a large load to high-voltage transmission is often the single biggest siting constraint, so seeing the grid on the map changes how you shortlist land.
Power Proximity Scoring
Every one of Texas's 14.3 million parcels is scored for distance to the nearest electric substation and the nearest transmission line, alongside natural gas pipelines, interstates, and rail. Power and infrastructure proximity is weighted at 30% of the composite site score, so the parcels closest to viable grid interconnection rise to the top of your search automatically.
Satellite & Hybrid View
Switch to a satellite-imagery basemap with a Google-style hybrid overlay — streets and labels drawn over the imagery — with parcel boundaries on top. Eyeball existing structures, nearby substations, and on-the-ground site conditions without leaving the map or ordering a separate aerial.
Substation & Transmission Distance Together
A parcel near a transmission line still needs a substation to interconnect. SiteData reports both distances for every parcel, so you can distinguish sites that merely sit under a line from sites with a realistic path to service.
Stacked Infrastructure Filters
Layer power proximity with acreage, county, land use, water service, natural gas pipelines, highways, and rail. Energy-intensive facilities rarely optimize for power alone — SiteData lets you find parcels that clear every threshold at once across all 254 counties.
Exportable Site Packages
Download parcel boundaries as KMZ, KML, or Shapefile for your GIS and engineering teams, and export a branded PDF report that includes a satellite image of the parcel. Everything you need to move a power-driven shortlist into diligence.
The power lines layer
Transmission, color-coded by voltage class.
Toggle the transmission layer on and the whole Texas grid appears on the map, drawn from HIFLD data and colored by voltage. Click any line to read its voltage, operator, and connected substations — then judge instantly whether a nearby parcel has a realistic path to interconnection.
Who uses SiteData for power siting
Built for energy-intensive projects in Texas.
Data Center Developers
Power is the gating factor for hyperscale and colocation sites. Filter Texas parcels by proximity to high-voltage transmission and substations, then confirm site conditions on satellite imagery — narrowing thousands of options to a defensible shortlist before engaging utilities.
Energy-Intensive Manufacturing
Chip fabs, steel, chemicals, and other high-draw facilities live or die on power access. Score sites for transmission and substation proximity alongside rail, gas, and highways to find land that can actually carry the load.
Site Selection Consultants
When a client leads with a power requirement, deliver ranked, transparent results instead of a static grid map. Filter, score, and export power-qualified Texas sites in one session — with the voltage class and distances documented per parcel.
Economic Development Organizations
Market a community's grid advantages with data, not anecdotes. Document which local parcels sit near high-voltage transmission and substations, and build power-ready site inventories for prospects chasing large-load projects.
How the score works
Power carries the most weight of any factor.
Every one of 14.3 million Texas parcels receives a composite score from 0 to 100. The Infrastructure dimension — which includes distance to substations and transmission lines alongside natural gas, interstates, and rail — is weighted at 30%, the largest single share. For power-driven projects, that puts grid-viable land at the top of your results.
FAQ
Common questions about power infrastructure siting.
How do I find sites near transmission lines in Texas?
On SiteData, toggle on the power lines map layer to see Texas's electric transmission network color-coded by voltage class, then apply the power proximity filter to your parcel search. Every one of the 14.3 million Texas parcels is already scored for distance to the nearest transmission line and substation, so matching sites surface in ranked order — no manual spatial analysis required.
Why does proximity to power matter for data centers?
For data centers and other large loads, interconnecting to high-voltage transmission is often the single biggest siting constraint — more decisive than land price or acreage. A parcel far from transmission and substations can face long, expensive interconnection timelines. SiteData scores both distances for every parcel and weights power and infrastructure proximity at 30% of the composite site score, so power-viable land rises to the top of your search.
What transmission voltage classes does SiteData show?
SiteData color-codes the transmission network by voltage class — 100–161 kV, 220–287 kV, 345 kV, and 500 kV and above. You can toggle the layer on and click any line to see its voltage, operator, and connected substations. Higher voltage classes generally carry more capacity, which matters when siting energy-intensive facilities.
Does SiteData score power infrastructure for every parcel?
Yes. All 14.3 million Texas parcels across every one of the 254 counties are pre-scored for distance to the nearest electric substation and the nearest transmission line, along with natural gas pipelines, interstates, and rail. These feed the Infrastructure dimension, which is weighted at 30% of the 0–100 composite score.
Can I see satellite imagery of a power site?
Yes. SiteData includes a satellite-imagery basemap with a Google-style hybrid overlay that draws streets and labels over the imagery, with parcel boundaries on top. You can visually inspect existing structures, nearby substations, and general site conditions, and the branded PDF report export includes a satellite image of the parcel.
Where does SiteData get its Texas transmission line data?
The transmission and substation layers come from HIFLD (Homeland Infrastructure Foundation-Level Data). SiteData overlays that network on State of Texas parcel geometry and precomputes each parcel's distance to the nearest line and substation. Texas runs on the ERCOT grid, and with power demand climbing from data centers and electrification, grid proximity is an increasingly decisive siting factor.
